writing a song is a particular skill that some people like albarn have in abundance. it hooks, melody structure etc... i think if someones a great songsmith they can be seen as being great at their craft without you necessarily being afan of their music.

albarn
murdoch
cocker
gallagher

pure songwriting, anyone could play those songs on and thhey would sound great. whether it be the sugrababes or nick cave.
